 /*
 openal.c TODO:
-1. AL_PITCH code does not work.
-   OpenAL alf_tpitch is currently broken. (Doesn't work with LOOPING, etc.)
-   Maps like Last Stand use it for (some rather odd) ambient sounds.
+1. AL_PITCH seems to work, but laststand is still a bit weird.
 2. Panning somewhat works now.  Need someone to verify.
 3. There is no EAX/Reverb.  But there's probably not much I can do...
 4. Restarting sound system may or may not work.
 5. Doppler (if it was originally used) isn't currently used.
-   Probably also broken in OpenAL (see 1).
 6. Better Error Handling (device not avail, etc).
